. plication scrimbe ze, 1e38, Seria lfi 1 3 3 3 Claims. (01. 123- 56) This invention relates to motor mechanism.

More particularly it belongs in the classof gasoline motors customarily termed two-cycle motors,

and has for its object'the production of a-motjor of special construction which is believed to pos sess unusual simplicity of design of the entire assenibly, and veryeconomical to build. The parts are readily assembled and easily and cheaply maufactured. The special construction of this invention is thought to eliminate valves, timing gears or chains, and cam shafts, while it has force feed lubrication; and can use an ordinary carburetor. The number of moving parts. in the complete assembly is at a minimum.

In the accompanying drawings are illustrated theconstruction'and disposition of the various parts, and Fig. 1 represents a top plan view of all the parts assembled. l

Fig. 2 is'a longitudinal vertical section through 39 two oppositely arranged cylinders and the crank case. M

Fig. 3 is a longitudinal section of one of the cylinders.

Fig. 4 is ,a sectional view taken on broken line 2 4+4, of Fig. 3. Fig. 5 is a sectional view taken on the broken line 5-5 of Fig.3. v

Fig. 6 is a Vertical sectional view showing the. oil pump structure on the crank shaft.

Throughout the drawings. and descriptionthe same number is used to refer to the same part.

In the drawings, Fig. 1, the cylinders I, 2, 3 and 4 are shown axially and oppositely arranged, with the transverse crank shaft 5 crossing the 85 crank case .6. Covering the top of the crank case is a hood 1 which will be again mentioned.

As. shown in Fig. 1 an oil pump 8, is mounted upon the crank shaft and driven by a pulley 9 on the shaft. Into the top ofthe pump is led a 40' tube or pipe connection I0 which is in open communication withthe bottom pan or cover ll 11- lustrated in Fig. 2. Oil collects in the bottom pan II and is drawn therefrom by the pump and discharged through tubular outlet I2 into a dis- 5 tributing oil pipe l3. This invention is not limited to the size or form of the tubular conduits. From pipe I3 a pipe l4 leads to the top or hood 1 of the crank case, and connects with a discharge tube l5 extending downwardly as shown in Fig. 2. Oil

50 collects in the crank case through orifices l6, and

in the bottom pan through like openings .I'L.

From the oilpipe 13 oil is delivered by way of tubes .18, I9, and 2| to the location of the cylinders, and each cylinder has a tube 22 in com- 65 munication with theinterior of the cylinder, as

set out in mg. 2.; It, will be understood that the pipe connectionjlfl shown in theFig. 1 extends 3 downwardly and connected with the bottom portionof the pan H which is. shown in Fig.2, so that the oil may be drawn by the pump 8 from the lowestpart of the mechanism into which i it has dripped throug h the openings Hillustrated'inFig. 2. l t W 3 Further considering Fig. 1, pulleys 2s and 24 drive water pumps such, as pump 25, and by way of conduits 26 cooling water is delivered'intothe water chambers 26 with which each cylinde'ris provided. Conduits similar to 26, not shown, may be located in connection'with the lower portions of the cylinders, in order that the cooling water may be circulated by the pumps and like. The

invention is not limited to any particularcon struction of water-pump or the necessary connecl tions. Pulleys 23 and 24 are belted to oil pump I pulley 9.

In Fig.1 are shown the external exhaust pipes 21 and 28, and inlet connections29 and 30, and in Fig. 2 are illustrated the piston 3| with rod 32 at the right, and the companion piston 33 with will be noted that the tube injecting the lubricant into the cylinder is inserted between the intake and exhaust ports as shown. This is held by applicant to be a simple and convenient arrangement, and is regarded as one of the points of improvement in this. invention. .No other or specific entrance for the lubricating tube is necessary- J As best shownin Fig. '3, the cylinder is further provided with the ports 39 and 40 connected by the by-pass 4|. l

Considering Fig. 6, it will be noted that the oil pump 8, driven by pulley 9, is provided with an eccentric 42, whichoperates a spring returned plunger 43, and the entrance of the oil is controlled by a -ball valve. 44. Applicant. holds that modified without departing from the scope of this invention. l f l In operation, starting when the charge has just exploded and when-the piston is at the inner end of its stroke as shown at the left inFig. 2, gas is entering through the intake ports due to the partial vacuum created by the instroke of the piston, as the cylinder is closed by the stuffing p the construction of the oil pump may be variously box of the crank case. Upon the opposite movement of the piston the intake ports are closed and the gas that has entered the cylinder is compressed by the movement of the piston. The gas is also compressed in the by-pass 4|. When the piston has moved all the way, the compressed gas travels into the cylinder through the ports 39. It is deflected by the fin or ridge on the head of the piston in an upward direction and turns down against the cylinder wall and forces the exhaust gases out by way of the exhaust ports 31. On the return stroke of the piston the gas is finally compressed and fired as the piston reaches the termination of its stroke. The operation repeats itself. At the same time, the oil pump and its connections lubricates the interior of the cylinder and discharges oil upon thecrank shaft and its connections in the crank case as herein described.

I claim: I

1. A motor having the construction comprising a crankshaft, cylinders oppositely arranged, a crank case between the cylinders, a crank slide and crank slide guide within the crank case, said cylinders havingpiston rods connected with the said guide, an oilpump mounted upon the said crank shaft and constructed to be operated thereby, oil tubes communicating with the interiors of the cylinders and' with the said pump, and an oil tube extending through the top of the crank case for discharging oil upon the crank slide and guide within the case and communicating with the said pump.

2. A motor having the construction comprising a crank shaft, cylinders oppositely arranged, the

said cylinders having cooling water chambers, a crank case between the cylinders, a crank slide and crank slide guide within the crank case, said cylinders having piston rods connected with the saidguide, an oil pump mounted upon the said crank shaft and constructed to be operated thereby, oil tubes communicating with the interiors of the cylinders and with the said pump, an oil tube passing through the top of the crank case for discharging oil upon the crank slide and guide within the case and communicating with the said pump, and pumps arranged to be operated by the said crank shaft and having connections with the said cooling water chambers of the cylinders.
